A simple, reproducible and efficient reversed phase high performance liquid chromatographic (RPHPLC) method has been developed for the estimation of a recently approved anti allergic drug, amlexanox in oral paste dosage form. The separations were carried out on a Zorbax Eclipse XBD, C18 column (150 x 4.6 mm; 5?m) at a flow rate of 1.50 ml/min. by using mobile phase comprising of mixed buffer (pH adjusted to 6.50) and methanol (50:50 v/v). The injection volume was 10 ?l and the peaks were detected at 244 nm. The linear dynamic range found to be in the concentration range of 15-35 ?g/ml and coefficient of correlation was found to be 0.999. The %RSD value was below 2.0 for intra-day and inter-day precision which indicated that the method was highly precise. The LOD (Limit of detection) and LOQ (Limit of quantitation) were found to be 3.8 ng/ml and 12.5 ng/ml, respectively which revealed that the method was highly sensitive. The percentage recovery of amlexanox ranged from 99.31 to 99.75%, indicating the accuracy of the method and absence of interference from the excipients present in the formulation. The proposed method was simple, fast, accurate and reproducible and hence can be applied for routine quality control operations of amlexanox in oral paste dosage form.

A novel reversed-phase high performance liquid chromatographic (HPLC) technique for the determination of everolimus (Isomer-B) and its impurities in the tablet dosage form has been optimized using analytical quality by design (QbD) approach. All the compounds are monitored with the photodiode array (PDA) detector at 280 nm and the parameters namely; precision, accuracy, specificity, stability, linearity, limit of quantitation (LOQ) and limit of detection (LOD) are evaluated. The quantitation limits of IMP-A, IMP-B, IMP-C, IMP-D, IMP-E, Sirolimus and TGR are found to be 0.08, 0.08, 0.10, 0.10, 0.10, 0.08 and 0.08, respectively. Recovery studies from 0.9 mg/L to 9.0 mg/L are performed for all impurities and the values were obtained between 85-110 %. Injection volume and test concentrations have been optimized to achieve LOQ values under the reporting threshold. The whole technique is developed and validated as per International Council for Harmonization (ICH) guidelines. The proposed method is robust, sensitive, rapid and successful and helpful in the regions where regulatory agencies recommend HPLC analytical method.

The aim of this work is to build up a fast, exact, precise and touchy reverse phase liquid chromatographic method for the synchronous assessment of amiloride and hydrochlorothiazide in tablet dose structure. The chromatographic strategy was normalized utilizing Hypersil ODS segment (250×4.6mm, 5μm molecule size) with UV discovery at 210nm and stream pace of 1ml/min. The portable stage includes phosphate buffer (pH acclimated to 2.5 with dilute Ortho Phosphoric acid) and acetonitrile in the proportion of 60:40 v/v. The linearity of proposed technique was examined in the scope of 5-30μg/ml (R²=0.999) for amiloride and 50-300μg/ml (R²=0.999) for Hydrochlorothiazide appropriately. The limit of detection (LOD) was discovered to be 0.10μg/ml and 0.40μg/ml for Amiloride and Hydrochlorothiazide appropriately. The limit of quantitation (LOQ) was discovered to be 0.30μg/ml and 1.20μg/ml for Amiloride and Hydrochlorothiazide separately. The retention times of Amiloride and Hydrochlorothiazide were found to be 3.258min and 2.383min separately. The technique was truly recommended and %RSD was found to be under 2 demonstrating serious level of exactness and accuracy. Subsequently proposed strategy can be effectively evaluated for the synchronous assessment of Amiloride and Hydrochlorothiazide in promoted formulations.
